Many scientists have attempted to organize the known elements to make sense of their properties and relationships. In 1789, French scientist Antoine Lavoisier published ... WebIt wasn’t until more than 40 years later in 1913 that British physicist Henry Moseley used a technique called X-ray spectroscopy to count the numbers of positive charges in the atomic nucleus. Moseley then developed the first modern periodic table, basing the element sequence directly on these charges.
WebMoseley found that there was a relationship between wavelength and atomic number. His results led to the definition of atomic number as the number of protons contained in the nucleus of each atom. He then realized that the elements of the periodic table should be arranged in order of increasing atomic number rather than increasing atomic mass.
